This study introduces an AI-powered algorithm for detecting cancerous breast masses on mammograms, improving early cancer diagnosis. The novel approach enhances mass visibility within dense breast tissue, aiding radiologists in identifying subtle tumors.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence in Healthcare
  • Breast Cancer Diagnostics

Background:

  • Cancerous masses in mammograms are challenging to detect due to camouflage by dense parenchymal tissue.
  • Accurate and early detection of breast cancer masses is critical for effective treatment and patient outcomes.
  • Existing mammogram analysis methods often struggle with subtle mass detection in heterogeneous breast densities.

Purpose of the Study:

  • To develop and validate an advanced algorithm for automated detection of cancerous masses in mammograms.
  • To improve the sensitivity and reduce false positives in mammographic mass detection.
  • To assist radiologists in identifying difficult-to-detect masses obscured by dense breast tissue.

Main Methods:

  • Integration of artificial intelligence (AI) techniques including fractal dimension analysis and the dogs-and-rabbits algorithm.

  • Application of discrete wavelet transform (DWT) for multiresolution image decomposition.
  • Utilized a tree-type classification strategy for final suspicious region identification.

    • Main Results:

    • The proposed AI-driven algorithm achieved a high sensitivity of 97.3% in detecting cancerous masses.
    • The algorithm demonstrated a low false positive rate of 3.92 false positives per image.
    • Verification performed on 322 mammograms from the Mammographic Image Analysis Society Database.

    Conclusions:

    • The combined AI and DWT algorithm effectively detects cancerous masses, even when camouflaged in dense tissue.
    • This automated approach shows significant potential for improving the accuracy and efficiency of mammogram interpretation.
    • The algorithm offers a promising tool for enhancing early breast cancer diagnosis through improved mass detection.
